I don't like to do that. It makes it inconvenient for people to reply.
Besides, name mangling (paulwadeATgreenbushDOTcom) is a form of surrender
to the abusers. I use traceroute and then abuse.net to file complaints.

That gets complicated because many people are at the mercy of a
technically challenged ISP. It would be great if everyone could get a
static IP with DNS.

Besides, anybody can subscribe to the list and never post a thing. Then
they just extract addresses from the messages that pass through.

A list server that requires a password somewhere in the message and
removes it before remailing would be nice.

Another spam generator is people using my domain names in false addresses
on usenet. I would need a program that scans 19000 newsgroups for domain
names in order to catch these people. They usually do this in the porno
groups and the email volume is high as a result.
